Helping to round out Kepler's middle-ground, NVIDIA today has unveiled its GeForce GTX 650 and 660 graphics cards. With the 660 Ti having been released not long ago, a non-Ti version might seem a bit strange so soon, but both cards are a fair bit different. While the Ti edition edges super-close to the GTX 670, the GTX 660 lands itself smack dab in between the new GTX 650 and the 660 Ti. And at $229, it could be the sweet-spot you've been looking for.
